Tennessee political king-maker Tom Ingram’s Washington D.C. venture, The First Group, is off to a brisk start this year when it comes to federal lobbying.

Public lobbying disclosures don’t tell the tale yet with how much retainers are running, but The First Group has signed an impressive array of clients, including some of the biggest names in American business to their portfolio of clients.

Capital One Financial, Visa, American Airlines, Anheuser Busch Companies, Eastman Chemical, the U.S. Chamber of Commerce and Ge Aviation all signed on with The First Group in the first quarter of this year.

Perhaps the biggest feather in their cap, though, is winning the business of BrightSource Energy, Inc. of Oakland, California. The company has partnered with Google to build the world’s largest solar power plant. Ironically, the project is getting some very focused scrutiny from California environmental groups concerned about the project’s impact on the local desert ecosystem.

The First Group partners are former chiefs of staff for members of the U.S. Senate, both Democrats and Republicans. Ingram is well-known in Tennessee for getting Republicans elected to statewide office, including Sen. Lamar Alexander, Sen. Bob Corker and Gov. Bill Haslam.

The First Group opened its doors in 2010. Last year, OpenSecrets.org estimated they collected over $500,000 in federal lobbying fees.
